Recode so that the conditions warned about are not reached.
Turning warnings off is the way to not get them displayed. Perhaps you were meaning that you do not want to turn all warnings off? if that is the case then you can turn warnings off selectively.

This snippet of code and the instructions (in comments) will help you to turn off specific warnings:
% Turn off this warning "Warning: Image is too big to fit on screen; displaying at 33% "
% To set the warning state, you must first know the message identifier for the one warning you want to enable.
% Query the last warning to acquire the identifier. For example:
% warnStruct = warning('query', 'last');
% messageID = warnStruct.identifier
% messageID =
% Images:initSize:adjustingMag
warning('off', 'Images:initSize:adjustingMag');
Adapt it for the warning you want to turn off by following those instructions in the comments.

I believe that one can prevent warnings without recoding or turning any warnings off by overloading warning. Something horrendous like
function varargout = warning(varargin)
varargout{1:narargin} = [];
end
